To all whom it may concern Be it known that I, ALTON L. WYMAN, a citizenof the United States, residing at Minneapolis, in the county of Hennepinand State of Minnesota, have lDYGZllQClCQ-ltftlil new and usefulImprovements in Combined Traction-Engines and Motor-Wagons, of which thefollowin is a specification.

My invention re ates to a combined traction engine and motor wagon, andhas for its object to provide a power plant which is adapted to beinterchangeably used either with the wheels and steering truck of atraction engine or with the wheels and front truck (als'l'fthe steeringtruck); of a motor wagon, the power plant and means of supporting thesame being such that when the same is used in connection with the motorwagon provision is made for supporting the wagon box directly upon thesupporting means for the power plant.

In the modern system of farming by means of power, there are threefundamental forms of operation which a farmer may accomplish by means ofa properly designed .power plant. First, by means of a stationmy powerplant such operations as threshing, shredding, cutting silage, pumpingwater, etc., may be profitably effected. Second, 'by means of a tractionengine having large and wide traction wheels of a well known type,operations of plowing, harrowing, seeding, and moving very heavy objectsmaybe accomplished. And, third, for transporting produce and othermaterials considerable distances over farm roads, a power plant appliedto a motor wagon is peculiarly desirable. But the average farmer cannotafford to own three separate power plants for performing the above setsof operations. It is, therefore, especially desirable to provide, ifpossible, and there is at the present time a great demand for, a

power plant which may be interchangeably used to effect any or all ofthe above sets of operations as desired and as the exigencies ofthe'cycleof farm operations may require.

It is the prime object of my invent-ion to provide apower plant whichmay be used either as a stationary plant entirely dissociated withwheels of any sort, which may be associated with traction wheels andused as a traction engine and which may, associated tical to the axis ofthe,main supporting-axle of the .ower plant; and also to provide means'or mounting on the same power], plant ordinary wagon traction wheelsadapted. to run and track in the commonf wagon roads of a farmingcommunity'and having the pitch andgather or inward slo 9- usuallyemployed in connection with t e.

To eflect this, it iswheels of a wa on. absolutely essential that thepower plant itself shall be practically compact and shall be secured ina unitary frame structure, allf parts of thepower plantincluding an ex-.

plo-sive engine, carburetor, muffler, radiator, fuel tank, and all othernecessary parts being supported in this single frame stnic:

tnre, and it is an object of my invention to provide a power plantcapable of use in producing such results.

It is a further object of my invention to provide a frame for the powerplant which may readily be connected either with a special frontsteering truck when the device is used for a traction engine or with anor dinary two-wheeled truck such as is employed in a farm wagon when themachine is to be used as a motor wagon.

It is a further object of my invention to provide a control mechanismfor the brakes, change speed and rererse of the transmission and a leverstand foroperating said control mechanism which may be positioned uponthe rear axle in connection with the power.

plant when the-machine is used as a traction engine and which mayreadily be changed in position and be applied to the hound of a frontwagon truck when the machine is used as a motor wagon, together withconnect-- tic-us from said lever stand which may be selectively appliedfrom the same when it is in either of its said positions.

It is a further object of my invention to provide a transmissionandcontrolsystemin combination with 'the interchangeable lever standsuch as can be readily opera-ted ineo'm' junction therewith when thelever stand -i'q i plan view liyend the rossbar 30 is bolted tothe saidtwo portions the st uh :raction steering, truck to produce atractionengine. Fig. 3 1s a plan'vlew and Fig. 4 18 of the interch'angeablelever r e in track. Fig, 18 is a ..carc.rld view partly in i 1 meetin toa ria t nll simllar to toot :20,

chine is us as a traction engine or as a motor w )1 respectively.

i it is a rurlher object of my invention to provide a front wagon truckin connection with the machine when used a motor wagon in which thewheelsare mounted on shafts of a divided axle and the steerihg may beeffected by oscillating said shafts as is usual in automobile structuresand also in which the front axle itself may oscillate about a kingboltin the manner being ellected through the short stubs and for lockingthestub axles when steering is of footed through the oscillation of thefront axle bodily.

The full objects and advantages oi? my invention will appear inconnection with the detailed description thereof and are particupointedout in thc'claims.

In. the drawingsillustrating a form 01" the appli lion. of my invention, Figure 1 is a and 2 is a side elevation of W invention appliedto traction wheels and a side elevation of the same parts applied to thewheels and trout steering truck of a motor wagon.- F 1g. 5 is anelevation v ew stand.

the power plant, is to be applied to a lraction engine and to a cast'mp,3; pivotall y connected with the king belt of the trout wagon truck whenthe power plant is to be used in connection with a motor wagon. Each ofthese castings 81 and 32 has identical angsr larly disposed wings and-l-l provided with shoulders 35 and 36 formingseats for the said ends ofportions 26 and 27. To change from. the traction engine steering truckto the motor wagon steering truck, therefore, would necessitate merelythe re moval of the bolts 37 by which the end P01" tions 26 and 27 aresecured to wings and 34: of one machine and the securing, of said boltsto wings 33 and 34; of the casting on the other machine.

The power plant comprising the motor 38, crank case 39, crank sh at't4-0, drive shalt 4:1, carburetor 42, fuel taut: l3,'mullier 4.4-, dii'.-ferential l5, and transmission system later to be described, all ofwhich are or may be of any well known construction, is rigidly supportedwholly upon the frame formed by the bars 15, i6, 2. and A rear axlemember similar co-pending application it Henry M. Kinney Serial Number(343,(64is employed which comprises a main transverse member 46 adaptedto receive upon its upper surface a wagon box when the power plant'isconnection with a motor wagon, said transverse member having integrallysecured thereto near the ends thereof depending, members 47 and 48 uponeach of which is also integrally secured at right angles to saiddepending; members axle stubs 1-) as most clearly shown in Figs. "l and155. 'lhcse axle stubs are conical in shape and somewhat inclineddownwardly, being in fact exactly the same as axle studs ordinarilyemployed for receiving the wheels of a common farm thisinclinat'rongiving the pitch and gather which permits the spokes "of the wheels of at'arznwagon to be bulged inused in wardly and yetextend vertically whendi the same is suspended upon the aforesaid rear axle member, whetherthe same thereto the. wheels of a traction engine or has applied andthis made through springs which traction wheels for a motor wagon,suspension is absorb the shock and jar incident to use of the powerplant for traction purposes in rough ground while neverthelesspermitting the drive to be accurately transmitted from the power plan tothe traction wheels.

As best shown in Fig. 13 when taken in connection with Figs. 2 and 4,the arms-47 and 48 have the lower portions 50 thereof partly cut away at51. so as to overlie the bars 15 and 1.6, a portion of the arms 47and 48extendihg within slots 52 formed in bars 15 and 16. 1 Through these endportions 50 rack and ultimate injury l6'and the 'power therefore, suspened from the axle strucmovement.

Figs. 2 and 13,

provided with a eyl extend bolts 53, said bolts also extending throughthe ends of strap yokes 54 of the form shown in Fig. 13 which yokes comebelow the central portion of heavy spring The ends of the springs 55 arepivotally secured to links 56 having hooks 57 which come into and engagein notches inthe lower edgesof the bars 15 and 16 as best shown I inFigs. 2 and 13. The frame members 15 and lant carried there-by are,

ture through the springs 55. The structure of th'e end members'50engaging in slots 52 in the bars 15 and 16 is such that verticalrelative movement of the axle structure and frame is possible, and onlysuch vertical The thrust of the wheels in driving the load istransmitted to the frame directly by the ends 50 in slots 52, while thepower from the power plant is conveyed to the traction wheels fromsprockets 58 on the drive shaft 41 through the sprocket chains 59 to thelarge sprocket wheels 60 on the traction wheels of the traction engineor of the motor wagon. While the relative vertical movement of the frameand power plant supported thereby with respect to the suspending axlestructurewill not be great, it will be suflicient to take up sudden andexcessive shocks and will be permitted by means of the connectionthrough the sprocket chain 59 between the power plant and the tractionwheels. As the shock and strain to which a traction engine and moreparticularly a motor wagon is subjected, in neither of which is thereany pneumatic tire or similar shock absorbing means, is necessarilyquite severe and liable to cause considerable to the mechanism of thepower plant, it will readily be seen that the shock absorbing suspensionherein provided is a matter of material advantage. Inasmuch as the powerplant heretofore de scribed is intended for upon either a motor wagon ora traction engine, and since the wheels of a. traction engine arematerially different in character from the wheels of a motor wagon,means are provided for readily applying to the transverse axle structuretraction wheels for the engine in place of the wheels for the motorwagon which are applied directly to the axle stubs 49. For this purpose,a sleeve 61 has formed therein a socket 62 adapted to receive the axlestubs 49, said socket being, as clearly shown in eccentricallypositioned so i that when the sleeve 61 is positioned on the stub axle49 the axis of said sleeve which is indrical outer surface, will fall ina line parallel to the top line of cross member 46, that is the elementsof the outer bearing surface of the sleevesGl are relatively horizontalwith respect to the axis the power plant. This is necessary be cause thetraction wheels 63 have Wide rims suspended by means of rods 64 in awell known manner, and the pitch and gather of wagon wheel constructioncannot apply to a wheel of that type. The sleeves 61 are firmly securedto the stub axles 49 by means of pins 65 extending through said sleevesand stub axles as shown in Figs. 1 and 13.

The wheels 66 for the motor wagon are similar to Wagon wheels in commonuse except that the tires may be specially constructed for tractionpurposes if desired. The hub and the spokes, however, are mounted intheusual way and the same are secured to the stub axles 49 by the usualnut screwed 011 to the threaded end 67 of said stub axle provided forthat purpose. The sleeves 61 form the bearings for! the traction wheels63 and have a threaded end 68 similar to the threaded end 67 on the stubaxles, the traction wheels being secured in. position by means of a nut69 screwed on said threaded end 68. To change from one set of wheels tothe other, therefore, it is simply necessary to remove the wheels thenin position and either take of wheels to its proper caring. Of course,the sprocket wheels 60 are secured to the respective sets of tractionwheels, whether for the traction engine or the motor wagon, and thesprocket chains 59 will need to be disconnected and reapplied wheneverthe sets of wheels are changed. As it is common to use sprocket chainswith interchangeable links, it is apparent that this part of the changecan be effected with the utmost ease. f it is desired to use the powerplant independently of any wheels, it is only necessary to drive thesame above proper blocking, jack up the power plant so as to remove thewheels, and wedge the blocking into position, or bolt the frame to saidblocking through flanges 70 on the frame members provided for thatpurpose. Upon the drive shaft 41 a pulley 71 is secured by means ofwhich power from the engine, when used for stationarypurposes, may betransmitted to any desired machine. This ulley is removably securedindicated at 72 and may be taken off entirely when the machine is leisused as a traction engine and will usually be removed when the machineis used as a motor wagon, as indicated in Fig. 3.

The transmission system employed in in present invention is in allrespects the same as that described and claimed in the copendingapplication of. Henry M. Kinney Serial Number 650,750, the lever systemfor controlling the same, however, is specifirally different from thatshown in the aforesaid application, and is particularly devised forapplicationeither to the rear axlemember 46 when the machine is fittedout as a traction engine or to the hound of a front i niorod to one orthe other of two active posiwagon truck when the machine is used for awagon. It will not be necessary, to more specifically describe the.traua-anisuimi than to stale that the spur gear 73 is last on a sleeveTl loose on the crank shal't ill, and that the clutch T5 splined on saidsleeve is adapted to engage the rluteh member 76 fast on the shaft fordriving the motor therefore,

The rod may, if desired, be made seetioual and united bymeans of belt or uni- '\'ersal joint, as indicated at 97, foroonvenience in removing from the power plant when changing the same tothe motor wagon.

When the power plant has the wheels 66 applied thereto extensfons 26 and27 of side frame membe s 16 and 17 will'be bolted to'the wings and 34 ofcasting 32.

The control system employed comprises a single leverhaving threepossible movements, any one of which connects with mechanism foroperating the transmission differentially. This lever mechanismcomprises primarily atubular stand 141v which is secured to a baseplatel42 said base plate having bolted in parallel spaced relationtherewith. a similar plate 143 as indicated most clearly in Figs. 5 and7. plate 142 beingprovided with amarginal flange 1-1-4 and plate 143with a similar marginal flange 145 so that when saidplates are securedtogetherby means of boltsf146' a housing is formed between'the plates.The-flanges 14 14 and 14-h extend around three sides of the, plates butare omitted on the fourth side sothat the chamber formed in the saidhousing is open at one side. The flange 145 .is integrally extended atone side in a lip147 and ,bi! means of bolts 1&8 extending-through suchlip and half openings in thefianges 144-.and

.145, the entire lever stand is nemovahlfviiisecured-either to the axle46 as shdwn in Figs. 1 and 2 or the hound of the wagon truck as shown inF igs. 3 and 4. To the top of tubular stand 141 is secured acup-likecylindrical head 14.9 to the top of which is bolted a cap 150.The cylindrical head has formed at one side thereof two peripheralgrooves 151 and 152connecterl bv a passae'e 153 extending from thecenter of groove 151 to one end of the groove 152.

Within the tubular member nu is a tuba-- lar sleeve 154 which hasieein'ed' thefeto in the housingjnrmed'by the plates 143. 144,-

a,'pair6'fdisks 155, 156. disk 155 having a pair of teeth 157 positionedon said disk at separated points thereof, while disk 156 is 156 with theteeth thereon. may be cast in n. single piece if desired. Through thecenter of sleeve 151 extends a shaft 159, the same being freelyrotatable-in sleeve 154 and having secured to thelower end thereof anarm 160. As shown. the arm 190 is without the housing formed by platesltil. 1.43, but it is praeti .-able to widen said housing and mount thearm 169 within the same beneath the disk 156 in whiehrase said arm wouldextend out throusrh the open end of the housing before mentioned.Secured to the upper end of sleeve 154: and within the cavity of the cupmember 149 is a hub 161 which has a shoulder 1'62 forming a bearing inthe bottom plate of member 149, the hub 161 being provided with an arm163 extending to a pointadjacent the slot 151 in the wall of member 149.Loosely mounted on shaft 159 and resting: upon hub 161 is a collar" 134provided with an arm 165.: Pivotally secured to the end of arm 165 bymeans of a belt 166 extending through arms 167 and'168 straddling thearm 165 is a levcr 169, arms 168 and 167 being integral extensions ofsaid lever and being expanded so as to embrace or extend about thecollar 164, and the exposed part of the hub 161. Above the collar 164and secured to shaft 159 is a hub 170 extending? from which is an arm171. the. arm 171 being: parallel with 'the arm 163 on hub 16!. Theloved 169 is held normally in balanced position between arms 171 and1.63 by means of a leaf spring 172 secured to arm 171 and a similarspring 173 is secured to arm 163. The. lever 169 is thus hcld not. onlyin balane 'd position between the arms 163 and '171 but within thepassage 153-1 between slots 1.51 and 152, which passage is ofapproxnnately the widthof the lever so that the margins of the walLofmember 14-9 at. such passage will normally hold the lever 169itrommovement. in either direction. The arm 163 is broad and provided with apair of wing-rs 174, 17') forming a space between the same adapted toreceive the shank of lever 169 when the same is pressed downwardlyagainstthe force of spring 173. The lever 171 is provided witheorrespomling wings 176 adapted to receive. between them the shank oflever 169 when the. same is pressed upwardly against the force of spring172. it will thus be seen that when lever 169 ispressed down betweenwings 174 and 175. itniny be moved in either direction in the slot 1'51;and when so moved will carry with it arm 163 which will 'oscillate thesleeve 154 in either of said directions. Notches 177 and !.78 are formed"above at the ends of the slot 151 for receiving and holding the lever169m either of its extreme positions. When the lever 169 is pressedupwardly between wings 176 on arm 171, it may be, moved in one directiononly in slot. 152. carrying with it the arm 171 which will thereby rockshaft 159 and arm 160. thereon. Upon a. post 179seeured .110

between plates 143 and 142 is pivoted a hub 180 "having on one sidethereof a segment 18] formed with two circular engaging portions 182,183 and an intermediate notch 184 for reeeii-ine the tooth 158 on disk156. Secured to huh 180 and extending away frmn-segment 181 is an arm185. Pivotally mounted upon post 179 above hub 180 is'a hub 186 havingthereon a. segment 1ST formed with two notches 188 and also formed withcircular engaging portions 189 similar to engaging portions 182 183; andfast on hub l86 and extending outwardly from segment- 181 is an arm 190.Journaled in brackets 191, 192. secured to the tubular stand'l il is arock shaft 193 having thereon a hand lever 194 and an arm 195.- Themember .49 is closed by a' cap 196..- All of the above parts arecomprised in the single removable lever stand secured by means of chineis to be used as a traction engine or a :1 and 3. traction engine andthe lever stand is semotor wagon.

The arms 160, 185, 190. and 195 are connected with the means foroperating the transmission and brake, as shown-in Figs. When the mach neis'used as a cured to rear axle 46 as shown in Fig. 1,

the arm 160 is pivotally connected by a linlr 197 with an arm 198pivoted at 199. and having an angularly extended foot 200 cugaging in a.notch 201 in a clutch lever 202. Thislever is fast on'a. rock shaft 203on which is an arm 204 for operating the clutch 75 for connecting themachine for fast speed ahead. This clutch 7!) is a. cone clutch andrequires a very small movement to effect clutching or unclutchingaction. The lever 202,-thercforc, requires a very small movement tobring about. through arm 204 the required movement and hence the notchor cam surface 201. on said lever will not need to be deep in order thatthe rocking of the foot 200 shall effect the necessary clutching andunclutching action. The ehitch 77 is operated by means of an arm 205 onaroek' shaft' 206 journaled vertically above rock shaft 203, as mostclearly shown in Fig. 13, said rock shaft having thereon anarm 207pivotally connected by link 208 with the arm 185, movement of arm 185 asshown in Fig. 1:

where connections are made for the traction engine in one directionplacing clutch 77 in one of its active positions while movement of saidarm in the other-direction puts clutch 77 in its other actiYe position.The drums 78. and 79 areeachprovided'with brake bands.

The operation of themachine whether. used as a traction engine or as a.motor;

"wagon will be substantially the same except that when usedas-ainotorwagon the high speed will be the one principally employed,

while when'used as. a. traetion engine the slow speed will be moregenerally used. The power plant, it will be observed, is

identical in eah casc, as is also the trans mission and control system.

This is by far the most expensive feature of either atraeti'on engineeramotorwagon so that having this power plant fitted up either for atraction engine or ya motorwagon; 5

The power plant is, therefore, strictlyinterchangeable there will becomparatively littleexpense to i the farmer toobtain thealternativepartsrequired, to titflthe powerplant for use. in 1 connection with the ot,.machinaandthe changa may be 'made 1th considerable ease and dispatch..Foi e ample, if'a-.farmer buys ai'tra'ction engine, as hereinillustrated,

work, wheels and steering wheels of a traction em,

traction wheels 66, the front wagon truck, and the extra connectinglinks217, 218,219 and 221 for the control device. To effect thetransformation from a traction engine to a motor wagon, he will firstremove from the traction engine the lever stand 141 and connected parts,and the steering truck together with the stand 95 and steering rod 90,replacing the wagon, which is accomplished merely by bolting the members27 and 26 to the wing members 33 and 34 on motor wagon truck casting 32.v the extension members 61 will then be removed from the stub axles 49and the motor wagon truck wheels 66 placed on said stub axles and gearedto the power plant by means of the sprocket chains 59. The lever standmay then be bolted to the hound 102 of the wagon truck by means of thebolts 148, and the proper connections made to the transmission and brakelevers by means of links 217, 218, 219, and 221. A wagon box of anyusual construction may then be placed upon the transverse member 46 andthe front hound 102 between the stakes 104. 105, respectively, the brace106 between the hound 102 and member 26 having first been bolted intoposition, if such brace is'employed. The transformation will then becomplete and the traction engine will have become a to be noted that forconvenience of assembling the box 103 on the hound 102 and transversemember 46, the steering shaft 136 may be socketed in the steering drum135 and inserted through a hole in the bottom of the box-and into saidsocket after the box has been placed in positior I claim.
